## Abstract Studies of the convergence and performance of the mixed finite element method in plane elasticity are reported. A completeness criterion is proposed, and convergence rates for stresses and strain energy, as predicted elsewhere, are quoted. An eigenvalue analysis of the mixed element mat
## Abstract A leastβsquares mixed finite element method for linear elasticity, based on a stressβdisplacement formulation, is investigated in terms of computational efficiency. For the stress approximation quadratic RaviartβThomas elements are used and these are coupled with the quadratic nonconfor
